Salesforce1 Add Standard Actions in page layout

Question

Does anybody know, how to add a custom (action) button like this? I just can use the default edit, delete an clone actions. Following the Salesforce1 App Guidelines , it should be possible to add custom actions to this section.

Answer 1

Indeed, it is true that most custom buttons will not be visible in the Salesforce1 context.

Custom buttons that DO work are those linked to a visualforce page where the standardController is set to the object on which your button is made.

Visualforce pages that don't use this standardcontroller won't work either.

Also keep in mind that your visualforce pages need to be marked as "Available for mobile". You can set this by going on your visualforce page through the setup area.

But be mindfull with the use of this... If you could achieve the same functionality via a publisher action (ex. create child records) with point and click, I would definitly advise to just use publisher actions instead.

EDIT since question is related to approvals in specific:

Approval processes and Salesforce1 is something that isn't fully integrated yet. So indeed, the "submit for approval" that you would normally get isn't available.

You can read more about it here:

and here

http://help.salesforce.com/apex/HTViewSolution?id=000187389&language=en_US .

I do know that you could submit a record for approval via code.

You can read all about that here, http://www.salesforce.com/us/developer/docs/apexcode/Content/apex_process_example.htm

So basically, you could create a visualforce page with a standard controller to your object where you put the code that submits your record for approval.

Answer 2

So my solution is a combination of the post publisher action.

and an trigger on the the Feed_Item object like this:

trigger Feed_Item on FeedItem (after delete, after insert, after undelete, 

after update, before delete, before insert, before update) {

if(trigger.isBefore && Trigger.isInsert) {
      for (FeedItem f : trigger.new)
      {
         if (f.Body.startsWith('!')) {
           System.debug('-#-#-#-#-#-#-#-#-#-: ' + f.parentId);
           approval.ProcessSubmitRequest aprlPrcs = new Approval.ProcessSubmitRequest();      
           aprlPrcs .setComments('Submitting record for approval.');
           aprlPrcs.setObjectId(f.parentId);
           approval.ProcessResult result = Approval.process(aprlPrcs);

           f.Body='Submitting record for approval';
         }            
      }
}

}

=> i can submit my Custom Object for approval by typing ! into the post field...
